STORM WINDOW.

Application filed March 28, 1923. Serial No. 628,205.

To all whom it may] concern.

Be it known that I, WILLIAM MILBRATH, a citizen of the United States, residing at Lakefield, in the county of Jackson and State of Minnesota, have invented certain new and useful Improvements in Storm Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a window structure and particularly to a storm window. Such storm windows or outside windows are now commonly used in the Northwest and other colder portions of the country.

The window commonly used comprises asash having therein one 'or more panes, which sash is of a size fitting the window casing so that the storm sash is substantially the same size asthe window casing. With this structure the storm window must always be placed in position from the outside and it is necessary to use ladders or scaffolding for the window in the upper stories. It is often necessary also to place the storm windows during bad weather so that. it is quite inconvenient work on the outside of the building.

It is an object of this invention, therefore, to provide a storm window of simple and eificient construction which can easily and quickly be placed in position from the interior of the building or window casing.

It is a further object of the invention to provide such a storm window composed of upper and lower sections, which sections can be moved through the sash openings of the window casing with the ordinary sash in the casing, together with means for holding said sections in position.

It is still another object of the invention to provide a storm window comprising the upper and lower sections, the upper section having hinges thereon and the lower section interlocking with the upper section for swinging movement relative thereto, and carrying means detachably engaging the hinges on said upper section. It is a still further object of the invention to provide novel and efficient means for holding the sections in place and for holding the lower section locked in position and in various positions of adjustment.

These and other objects and advantages of the invention will 'be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in; which,

Fig. 1 is a view in front elevation of the window casing showing a storm window in position as viewed from the inside;

Fig. 2 is avertical section taken on the line 22 of Fig. 1;

Fig. 3 is a view in front elevation showing the window casing and storm window in place as viewed from the outside;

Fig. 4 is a fragmentary section taken on the line 14 of Fig. 1 and shown on an enlarged scale; and

Fig. 5 is a horizontal section taken on the line of Fig. 1.

Referring to the drawings, an ordinary window frame or casing is shown comprising side members 1, a bottom sill 2 and a top cross member 3 and the usual upper and lower sliding sash l" and 2-, respectively. The outer bead or strip of the casing which extends along the sides and across the top thereof adjacent its outer side is shown as 4. The storm window comprising the present invention includes an upper section or sash 5 adapted to fit in the window casing and against the outside of the bead or strip 4 and a lower section 6 also adapted to fit against said bead. The top portion of the bead 4 has projecting downwardly therefrom at spaced points somewhat adjacent its side portions, pins 7, and the top portion of the upper section 5 has small angle brackets 8 secured to the inside thereof, the top plates of which are apertured to receive the pins 7 to prevent outward movement of this portion of the section. The bead or strip 4 also has projecting inward therefrom at intermediate points the pins 9 and these pins are adapted to project into slots 10 formed in U-shaped brackets 11 secured to the front sides of the section 5 adjacent its lower edge. Each bracket 11 has pivoted other toward their outer or free edges so i that the same bind against the sides of the bracket 11 and snugly fit the pin 9 whereby a clamping action is obtained and a locking device formed having no free movement so that there will be no rattling thereof. The upper section 5 has secured at the bottom of its side portions on the outside thereof, hinges 13 which have their lower butts or flanges provided with slots 14, which slots, at their upper portions have parallel sides 14 which curve outwardly at their lower edges. The upper sash .is also preferably provided with a semi-circular groove 15 extending across its bottom edge and the lower section or sash 6 is provided with a corresponding rib adapted to fit in such groove. Said lower section also has secured in its side portions adjacent the top thereof bolts 16. Saidbolts have heads at their outer portions illustrated as of rounded or buttonhead type and square shanks adjacent said heads. Said shanks each extend through a square hole formed in a plate 17 secured to the outside of the section and the inner and threaded portion of the bolt extends through a rounded hole in a plate 18 screwed to the inside of the sash. The squared portion 19 of the bolt is contacted by a coiled spring 20 surrounding the bolt and disposed in a recess formed in said sash, said spring contacting the plate 18 at its inner side. Itwill thus be seen that the spring 20 tends to push the head 16 of the bolt outward from the sash, this movement being limited by the clamping wing nut 21 threaded onto the bolt at the inside of the plate 18. The squared portion 19 of the bolt is adapted to fit in the'slot 14 of each of the hinges 13 and the lower section will thus be hingedly connected to the upper section, the nut 21 being securely tightened to hold the sections in this position. The lower section 6 has secured to one of its side portions adjacent its lower edge a small bracket 22 having projecting ears between which is pivoted the end of a locking arm 23, which arm for its major portion, is of angular shape in cross section, and has one flange provided with spaced notches 24, which notches are adapted to be individually engaged over a screw head 25 projecting from the head 4 adjacent its bottom portion whereby the lower section may be held in various open positions. When the lower section is swung to tightly closed position, the arm 23 will be swung the arm 23. A

upwardly to lie along the side ed e of the section anda small swinging mem er 26 is pivoted to the side of the section above the end of said arm,which. member is of angle shape in cross section and one side of which is adapted to swing over the upper end of plate 27 of angle shape in cross section is secured to the bead 4 so as to have one side thereof projecting between the arm 23 and thefront side of the member 6. This plate causes the arm 23 to incline toward the inside of thecasing and the upper end of said arm must be pushed tight against the plate 27 and sprung slightly to be engaged by the swinging member 26. This tight springing engagement causes the mem- .bers to be held tightly and securely in position and prevents any tendency of the same to rattle. The section 6 is also provided at its other front side adjacent the bottom thereof with a plate 11 and lever 12, similar to these parts described in connection with the upper section 5,.which parts co-operate with another pin-9 projecting inwardly from the bead 4. The lower section is also provided at each front side somewhat adjacent the top with swinging bail-shaped handles 28 having their ends extending through angle plates 29 securedto said sash.

With the parts as shownand described, when itis desired to place the storm window in position, the usual upper sash 1 of the window will be lowered. The upper section 5 can thenbe passed through the sash opening and the holes in the brackets S'engaged over the pins 7. The lower part of the section will then be swung inwardly so that the brackets 11 engage over the pins 9.. The levers 12 will then be swung to locking position and the upper section will be held in place. The usual lower sash 2 of the window can now be raised and the lower section 6 passed-through the lower sash opening. The nuts 21 will be loosened and the heads 16 will therefore be projected beyond the plate 17. The section can now be held by the handles 28 and the squared sections 19 of the bolts slid upwardly into slots 14 of the hinges 13 and the top portion of the section 6 brought into close engagement with the groove 15 of the upper section.

The wing nuts 21 will now be tightened and the lower section will thus be firmly clamped and secured to the hinges on the upper section. The springs 20 will assist in holding the belts in firmly clamped position so there will be no tendency of the nuts 21 to work loose. The lower part of the section 6 can now be swung inwardly to closed position and locked in tightly closed position by the parts 23 and 26 as well as the parts 9, 11 and 12, or said window can be placed in the desired open position by engagement of one of the notches 21 over the headed screw or bolt 25. The storm window is thus easily and applicants quickly installed from the inside'of a building and will remain securely in position as long as desired. The lower section 6 can at any time be opened or closed for ventilating purposes. It will be obvious that sections of the window also may be taken down with the same ease and rapidity with which they were put up by merely reversing the operations above described.

From the above description it will be seen that applicant has invented an inexpensive, simple and efiicient storm window structure. lVith such a such a structure, the serious objection of placing the storm windows from the exterior of the building is overcome. The storm window canbe easily and quickly placed in position by any person" and it will not be necessary to wait for the services of a carpenter or. other mechanic who must use a ladder or scaflolding to place the windows. If desired, the ad'ustable arms 23 may be placed on each si e of the window tohold the same in itsvarious open positions. It will be seen that by theprovision of the semicircular groove 15 and the part fitting therein that the sections can readily swing throughthe desired angle relative to each other and that a very tight joint is provided which will effectively pre-j' vent the passage of air:

It will, of course, be understood, that various changes may bemade in the form, details, arrangement and proportions of the parts without departing from the scope of invention, which, generally, stated, consists in a device capable of carrying out the objects enumerated and as shown and described and set forth in the.
